Referring to heI drawings in detail, my iinjorovefl valve consists, generally, of a Using divided into :i pressure chamber and 'valve chamber (l, the letter cheinlier liar' o' inlet 10, a discharge passage 1l, 'Li-nfl e, \v'nl've sont 12 therebetween. The easing is divided into the chambers ll and C by :i diaphragm l) to which is secured ,he mein vulvev E eclnpiecl to cooperate with he seni l2. Located in the discharge portion ci? the casing is the auxiliary Valve F .vhich is manually Controlled 'oy the oper- !.iiug mechanism (l to relieve the pressure n he chamber ,he veli-re. ln the present illustrative disiosnre of ,my invention, the casing comirises 4 ports or sections, namely, mein body ifiin which the mein valve E is located. cap l5 which provides lshe pressure chamber, and e discharge section io the ourlet side of the valve sean l2, unil which discharge section carries che relief valve andA the operating; mechanism therefor, es hereinafter' described more in lei-rail. The n 'l5 is screw threacle, as all l?, onto the mein body l, and the man gin-al edge of the diaphragm is clamped betr.' en this een and the main body, ln. order lio Lnsure hei; ille diaphragm will noi, be pulled loose, the een is, hy preference` 'formed with eu annuler heedl or rib 18 which, when the can is screwed home, is pressed into the diaphragm, sherehy Securely holdingf it in place. houi'r the circumference o? the can l5 is e resilient ring r9. of rubber or the. like against which the sea or che closet engages when it is in raised position and, thus, damage to the seein by being?, lirown against the metal of the flush vulve is guarded against. ln the present illuszretire disclosure, this rubber rino; 19 is seared in zi (lovetail groove in `lie perimeter of rhe een.

Secured to rho under eide ofi" elle cliephagm D is the mein Ynlvc E which, by preference. is of reduced diameter between its ends. The valve is secured to the Clie,- phraggm B in any suiuhle manner, as loyineans of screws 2:2 which pass through a rereining or weer pluie on the upper sicle ebree ll when it is desired to ush whioh is .in ibheor'zs flislq, may he insges han the upper: enel of the valve E, es shown.

The valve head of this enxiliasy valve as shown in Figs. l? 3 and 4, is in she form of a hollow cone 38 of leather orwhe likey and uhis cone end of he siem 36 by a sap nut 39 which has a oioumferenbial flange 40. Between the' orosspieee s? and ehe nut 39 is e oompression ing el which nol'mally urges the -elief .f'alve upwardly towards is seat, 35

on the moin valve.

The mechanism, hy which the relief valvelopermsd to elle@ the desired flushing, comprises, genit-rallye a pivo'fed lrgger 45, s plunger el end a handle 4l? so arranged thai when the handle is rocked the plunger 4f?) in a direction to Wifchdraw he relief valve from its seat. Whereupon the pressure in lhe chamber B isrelieved, perniiting the pressure. wihin he chamber C 'to zaisethe diaphragm and eheA valve carried 'llherehy ln the present instance, `ihe trigger is in the formL of an angle lever pivoted bye pin 48 to lugs or ears 49 extendingforvardly from a smiling box 50 which supports and guides the plunger 46k The pin 48 is held iigainst` remmml 1w :i coller 51.. arm of bhe .arm of the lever is in the form of is secured lo the upper.

The diaphragm and.

:heisses verllf, `which cooperates with elle reli'e valve is forked or pronged, as shown most clearly in Fig: 3. The ends of these prongs engage and ride upon the lange 4() of the relief valve. .lt will los nosed that there is no rigid' connection oelween the lever l5 and the relief valve, thus permitting she relief valve to adjust iaself to the valve seat 35. The relief valve is free to turn so that weer Will be evenly distributed thereon. The other an ups-Ls-nding lun` which is in line with the plunger 46. Leakage of Water abou?, the plunger 4G is guarded against by the packing and the packina1F gland 56 held in place in the stuiling box 50 1oy a cap nut 57. The stuffing hoi; 50, together with the parts carried thereby, is hold in place by a cylindrioal sleeve 55s. ehe forward end o which is threeclnl into a lhroaded opening in the side ol the discharge section 1G. The outer end of this sleeve 58 is turned inwardlylio provide a retaining :lange 59 against which engages a rib or flangel 60 on the rocking! handle 4T. rl'lie inner end of the handle 47 is provided 4with a convex recess in which engages the round head 61 of the plunger 46. The handle 4T and the plunger 4:6 are nox" molly hold in their a compression spring 62 located heween lsho cap nut 5T and the head of the plunger-46.

'lhe operation of he device is briefly as follows. lll/'hen the handle 4l? is rocked in any direclion, the plunger 46 is moved forwardly against the upstandinw arm of the lever 45, thereby rocking; his lever in a direction lo move, the relief valve downwardly away from tlielvalve seat 35. As the Water passes from the pressure chamber E hrough lhe port 28, the pressure within this chu-m- 'herf reduced7 whereuponthe greater pres sure Within the 'valve chamber C will raise l sis The main valve is connested to the diaphragm. the main valve is moved: upwardly from is seat., whereupon the' Water is free to now directly from the inlet to lhs discharge opening. The upward travel of 'che main valve is limited by a. stop provided in the cap 15, in the present instance this slop losing in the orinof a depending' cylindrical boss 64; against the =-lo\ve.r end of which the retaining plate 23 is adapted to engage. `The main valve will remain in its raised position, during which time the Water will continue to lowthrough ehe valve, until the handle 47 is released, whereupon the spring 62 will force the plunger 46 away from the lever or trigger 45. and slie spring 41 will cause the relief valve 13o move upwardly int-o engagement *Vith its seal 35, as shown 'in Fig. 2.- The flow or" Water through the relief pori; 28 is not shut off so i'zhat. the pressure Within the chamber E will built up to such en extent ss inoperative positions by io more than oounterlielanoe the pseure in los 'eood, l "het by adjusting "che e valve thereby controlling' 'the l lion? o) r E, the time required for closing the nein valve, the handle is released, may regulan l, end to that extent the nsh be automatically controlled. -s will he seen from the foregoing descripi'ion, baken in connection with the accom-n "yingr drawings, that the relief valve and the operating :mechanism therefor are cer ried by the section 'lf3 of the valve casina This section may he readily dissembled from the body lei. ny removing lhe screws 65 which pass through a flange at the upper end of 'lhe section ill and are screwed into suitable ihr 'ed holes in the bottom o the mein seccion le. lreierahiy, the holes which receive 'ehese screws 65 are spaced apart at equal angles, for instance, if there are four such holes'in the flange, there will be four similar holes in the body 14, and the holes will he spaced ninety degrees apart. "This arrangement is of edvantage in that it permits of angular adjustment of the section lo on the body porbion 14. ln the present in stance, the section 'i6 may be secured to the body lll in Jfour di'erent positions, and that position will be selected which will permit o the most convenient operzition of the handle 47. lt will be further noted that the operating; mechanism 'for the relief valve may be very quickly assembled and taken down. in the event that it is desired to repair or renew any the parts ol the valve mechanism, is merely necessary to unscrew the 58 from the section 16 and then Witl-n draw 'the smiling hox arrangement from po sition. is the trigger 45 is carried hy 'the etufiing box, it is removed therewith. lt is easy to attach and detach the trigger trom the slniiinej box. Thus, it will be seen/thai the arrangement is a very simple one, 'and the construction is such that the parts-may be cheaply made and quickly assembled.
